CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application No. 61/689,260 filed on May 31, 2012 entitled Dahlia plant named ‘Mystic Fantasy’.

GENUS AND SPECIES

Dahlia variabilis

VARIETY DENOMINATION

‘Mystic Fantasy’

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of dahlia grown for use in mixed combinations, beds and the landscape. The new invention is known botanically as Dahlia variabilis and will be referred to hereinafter by the cultivar name ‘Mystic Fantasy’. This application is co-pending with the application for the inventor's variety of Dahlia plant named ‘Mystic Memories’.

The specific epithet variabilis represents a hybrid seedling line that came from crossing various original wild species in the early 1800's, and refers to the species' wide range of flower color and shapes. Dahlia is in the family Compositae. The flower of ‘Mystic Fantasy’ is a “single” form blossom and exhibits a single row of ray flowers surrounding a central cluster of disk florets.

‘Mystic Fantasy’ was selected as a seedling that resulted from the controlled cross-pollination carried out by the inventor in a cultivated area of Auckland, New Zealand in 2007.

The inventor selected as female parent an individual plant of the inventor's variety Dahlia variabilis ‘Fifteen Love’ (unpatented). The chosen male parent was the inventor's variety Dahlia variabilis ‘Knockout’ (U.S. Plant Pat. 18,339). Seed was collected from the female parent and sown with the intention of making a selection from the seedlings that resulted.

‘Mystic Fantasy’ was selected in 2008 based on the criteria of leaf color, leaf shape, plant height, self supporting plants, single blooms and flower color. Selection was conducted by the inventor, in Auckland, New Zealand. The unique traits that distinguish the new Dahlia variety named ‘Mystic Fantasy’ from other varieties of Dahlia known to the inventor are glossy mahogany-black divided leaves and flamingo pink single flowers with a soft yellow halo, raspberry eye and dark central disc.

The first asexual reproduction of ‘Mystic Fantasy’ was conducted in 2008 in Auckland, New Zealand. The method of asexual propagation utilized was softwood cuttings taken from the one year old tuber of the original selected seedling. Since that time under careful observation, the distinguishing characteristics have been determined stable, uniform, and to be reproduced true to type in subsequent generations of asexual propagation.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Dahlia cultivar named ‘Mystic Fantasy’. These traits in combination distinguish ‘Mystic Fantasy’ from all other existing varieties of Dahlia known to the inventor. ‘Mystic Fantasy’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

1. ‘Mystic Fantasy’ exhibits a compact rounded habit.

2. The foliage of ‘Mystic Fantasy’ is glossy mahogany black in color.

3. ‘Mystic Fantasy’ bears flamingo pink flowers with a soft yellow halo, raspberry eye and dark central disc.

4. The flowers of ‘Mystic Fantasy’ are single.

5. After one year of growth, plants of ‘Mystic Fantasy’ are 60.0 cm in height and 30.0 cm in width.

6. At maturity, plants of ‘Mystic Fantasy’ are 80.0 cm in height and 60.0 cm in width.

7. ‘Mystic Fantasy’ prefers a rich moist well-drained medium.

8. ‘Mystic Fantasy’ is hardy in USDA Zones 9 and higher.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

The new Dahlia named ‘Mystic Fantasy’ is distinguishable from the parents predominantly by flower and foliage color. The flowers of ‘Fifteen Love’ are of collarette form (that is, bearing a collar of petaloids stamens around the disc) and uniformly orange-red in color. The flowers of ‘Knockout’ are single and uniformly yellow in color.

The variety of Dahlia which is considered by the inventor to most closely resemble ‘Mystic Fantasy’ is Dahlia ‘Mystic Memories’ (U.S. Plant Patent Application pending). The flowers of ‘Mystic Fantasy’ are flamingo pink with a soft yellow halo, raspberry eye and dark central disc, while the flowers of ‘Mystic Memories’ are soft peach with orange-red highlights.

BRIEF DECRIPTION OF THE DRAWINGS

The accompanying color drawings labeled FIG. 1, FIG. 2 and FIG. 3 illustrate the overall appearance of the new Dahlia cultivar named ‘Mystic Fantasy’ showing the colors as true as is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describes the actual colors of the new Dahlia variety named ‘Mystic Fantasy’. The photographs were made from digital photographs of four months old from a cutting plant grown outdoors in Santa Barbara, Calif.

The drawing labeled FIG. 1 depicts the entire plant in bloom and demonstrates that the foliage of ‘Mystic Fantasy’ is consistently mahogany-black when grown in full sun. Any part of the plant which is in shade, including the shade of other plant parts, turns to olive green in color. This coloration is reversible such that the olive-green foliage returns to mahogany-black when exposed or re-exposed to full sun.

The drawing labeled FIG. 2 depicts a close-up view of the face of a flower of ‘Mystic Fantasy’ showing the flamingo red petals and dark central disc.

The drawing labeled FIG. 3 depicts a close-up view of the reverse of a flower of ‘Mystic Fantasy’ showing the dark translucent phyllaries and parallel pink-red veins.

The drawings were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Dahlia cultivar named ‘Mystic Fantasy’. Observations, measurements, values and comparisons were collected in Santa Barbara, Calif. from a 12-month-old plant grown in the landscape. Color determinations were made in accordance with the 2007 Royal Horticultural Society Colour Chart from London, England, except where general color terms of ordinary dictionary significance are used. Growing requirements are similar to the species.
